134449 - View->Text Zoom can misrepresent actual text size percentage.

Status: NEW

(SeaMonkey :: UI Design, defect)

Description

[J.B. Nicholson]

Mozilla 2002032803 on Windows 2000.

Using View->Text Zoom->Other... you can set the magnification below what's the
visible text zoom size.  In other words, View->Text Zoom->Other... doesn't stop
at the minimum font size (set in Moz's preferences).  The font size doesn't
actually render below minimum font size but the menu item can be set to
arbitrarily low zoom percentages.  This is clearer with an example:

1. Open a Mozilla window or tab and use Moz preferences to set a minimum font
size (I set 16--the largest minimum font size available).
2. Open a webpage with lots of text.  http://www.mozilla.org/ is fine.
3. Use the mouse wheel to set the font size low (or use Ctrl+- to shrink the
text).  Eventually you hit a point where the text won't shrink any further; you
have hit the minimum font size.
4. Select View->Text Zoom->Other... to set the percentage to something smaller.
 The webpage will not look any different but the percentage will misrepresent
the visible rendered text size.

Now you're seeing the bug--the text is actually at x% of normal but the
View->Text Zoom->Other... menu choice (which has a dot next to it indicating it
is current) says it is set to q%.

To XP apps.  There's really nothing that can be done here....  We can't tell 
that a particular percentage of will cause all text on the page to be below the 
minimum size unless we walk all the text on the page and look at all the sizes, 
which is painfully slow...

confirming, ccing UI people to decide what, if anything can/should be done here.
 Perhaps text zoom should ignore the minimum font size setting?  (that seems
wrong to me, but....)

Looks like an unexpected side-effect/regression from some other work that dbaron
did. (my recollection is that the zoom is expected to be after-the-min-size).
Cc:ing dbaron & hixie for follow-up.

uid is being phased out.

Reassigning obsolete bugs to their respective Seamonkey owners (i.e. nobody). 
If you want this fixed for Firefox, change the Product and Component accordingly
and reassign back to me.
